“…The biodegradation of lignocellulosic materials by a fungus primarily occurs in an extracellular form, since they must initially be depolymerized to smaller compounds to be susceptible to be transported by the cell wall and intracellular fungi metabolism. Moreover, fungidegrading action occurs through penetration of their hyphae in the lumen of the plant cells (Rodríguez et al 1997); afterwards, their hyphae produces a great diversity of extracellular metabolites, which then act by degrading the plant cell wall.…”

By seeding fungus on top of industry residues, a mycelium can grow and form a compact network structure; however, it may not develop due to lack of optimal nutrients from the substrate. Consequently, peach-palm residues can be a potential alternative; so, to test this hypothesis, this work evaluates the effect of peach-palm residues as substrate for the growth of mycelium based on Lentinula edodes. They were also supplemented with cassava bran and various sources of nitrogen-ammonium sulphate, potassium nitrate, and soy flour—to analyse its effects on its physico-chemical, enzymatic activities, and thermal and mechanical properties of the final composite at 12 and 20 days of cultivation. This mycelium was able to grow at optimum source treatment conditions, which depends on the ratio of Carbon to Nitrogen, within only 12 days of inoculation. Furthermore, the enzyme activities directly correlate with the mycelium growth with optimum conditions of pH, water activity, and moisture for L. edodes to grow having lower enzyme activities for a well-developed composite; whereas higher activities were seen for a weakly developed material, and this material demonstrates mechanical and thermal properties similar to common mycelium-based composites. Therefore, this work demonstrates that peach-palm residues can be a potential alternative for mycelium-based composite.

“…Other factors, like the amount of nitrogen, should be taken into account when biological pre-treatment is considered. When white-rot fungus is used for pre-treatment, nitrogen limitation would be preferable, as higher glucose consumption is associated with excess nitrogen [22]. Although fungi as decomposes are well known, there has been proof that bacteria could be used for decomposition of lignin as well.…”

Due to growing topicality of indirect land use change, greater shift towards second generation biofuels should be observed. In order to help smaller biogas and bioethanol producers, multi-criteria analysis of lignocellulose pre-treatment is conducted to elucidate the most preferable approach for lignocellulose pre-treatment. There are four main pre-treatment groups – biological, chemical, physical and physochemical pre-treatment. In this article three pre-treatment types were described by highlighting their specific approaches; using multi-criteria analysis a conclusion was reached that the most preferable pre-treatment option for lignocellulose biomass like corn stover or sugarcane is microbiological pre-treatment, as it showed the closest proximity to ideal solution.
